WARNING - Ignition key (smart key)

Never leave the keys in your vehicle with unsupervised children. Leaving children unattended in a vehicle with a manual ignition key or a smart key is dangerous. Children copy adults and they could place the key in the ignition switch or press the start button. The key would enable children to operate power windows or other controls, or even make the vehicle move, which could result in serious bodily injury or death.

Locking

Pressing the button of the front outside door handles with all doors (and hood and trunk) closed and any door unlocked, locks all the doors (and trunk).

The hazard warning lights will blink once to indicate that all doors (and trunk) are locked. The button will only operate when the smart key is within 0.7 ~ 1 m (28 ~ 40 in.) from the outside door handle. If you want to make sure that a door has locked or not, you should check the door lock button inside the vehicle or pull the outside door handle.

Even though you press the button, the doors will not lock and the chime sounds if any of the following occurs:

• The smart key is in the vehicle.
• The ENGINE START/STOP button is in the ACC or ON position.
• Any door except the trunk is opened.

Unlocking

Pressing the button of the driver's (or front passenger’s) outside door handle with all doors closed and locked, unlocks the driver's door.

The hazard warning lights will blink twice to indicate that the driver's door is unlocked. Also, the outside rearview mirrors will automatically unfold if the outside rearview mirror folding switch is in the AUTO position.

The button will only operate when the smart key is within 0.7 ~ 1 m (28 ~ 40 in.) from the outside door handle.

When Two press unlock function is activated,

- If you press the driver's outside door handle button, the driver's door will unlock.
- If you press the driver's outside door handle button within four seconds again, then all the doors and trunk will unlock.

✽ NOTICE

You can activate or deactivate the Two Press Unlock function. Refer to “User settings” in this chapter

Trunk unlocking

If you are within 0.7 ~ 1 m (28 ~ 40 in.) from the outside trunk handle, with your smart key in possession, the trunk will unlock and open when you press the trunk handle switch.

The hazard warning lights will blink twice to indicate that the trunk is unlocked.

Also, once the trunk is opened and then closed, the trunk will lock automatically.
